Vichy authorities allowed aircraft from the German Air Force (Luftwaffe) and the Italian Royal Air Force (Regia Aeronautica) to refuel in Syria and Lebanon before and during the Anglo-Iraqi War. After this, the Allies planned an invasion of the French mandates.

Fighting continued in Lebanon but the Vichy forces continued to lose ground. By July, the Australians were nearing Beirut. The fall of Beirut, the capital of Lebanon, meant the end was near. On 10 July 1941, as the Australian 21st Brigade was on the verge of entering Beirut, Dentz sought an armistice. At one minute past midnight on 12 July 1941, a ceasefire went into effect. During the ceasefire, Dentz ordered ships and aircraft under his command to go to Turkey where they were interned.

For all intents and purposes, the ceasefire on 10 July 1941 ended the campaign. An armistice, known as the Armistice of Saint Jean d'Acre, was signed on 14 July 1941. There were 37,736 Vichy French prisoners of war who survived the conflict after fighting for Dentz. Most chose to be repatriated to Metropolitan France rather than join the Free French.
